Salts and Solubility Activity 5 Learning Goal for 5: Students will be able to predict what would be observed on a macroscopic and microscopic level for salts with varying ionic charge given the K sp. Trish Loeblein July 2008.

1.Which will have more dissolve particles in a saturated solution? K sp =3 E –13 A compound made from A. XY B. XY 2 C. no difference

Answer to 1 XYXY 2

Why doesn’t the mass of the particle matter?

2. Which will have more dissolve particles in a saturated solution? K sp =2 E –15 A compound made from A.X +1 and Y -1 B. X +2 and Y -2 C. no difference

Answer to 2 XY

3. Which will have more dissolve particles in a saturated solution? K sp =2 E –15 A compound made from A.X +2 and Y -2 B. X +2 and Y -3 C. no difference

Answer to 3 If you run the sim at the default volume, you cannot get the second compound to ppt, but only 4 dissolve of the first. X3Y2X3Y2 XY
